Learn More About Shampoos For Scalp Psoriasis

Shampoos for scalp psoriasis can help loosen thick scales, reduce itching, and improve the appearance of irritated skin. The most appropriate shampoo depends on the severity of the psoriasis and the ingredients it contains. The American Academy of Dermatology identifies coal tar and salicylic acid as ingredients commonly used in psoriasis products, including medicated shampoos.

How Shampoos Can Help Scalp Psoriasis

Scalp psoriasis can cause raised patches, scaling, itching, and irritation. A medicated shampoo may help soften and remove scale while treating some of the symptoms. 

Common shampoo ingredients include:

• Salicylic acid: Helps soften and remove thick scales.
• Coal tar: Can help reduce itching, scaling, redness, and inflammation.
• Other medicated ingredients: Some prescription shampoos may contain medicines specifically selected by a dermatologist.

The best option depends on the individual's symptoms and the recommendations provided by a healthcare professional.

What To Know About Salicylic Acid Shampoo

Salicylic acid is often used for scalp psoriasis because it can soften thick, stubborn scales. Removing excess scale may also help other topical medicines reach the affected skin more effectively. 

When using a salicylic acid shampoo:

• Follow the product directions carefully.
• Apply it to the scalp rather than only the hair.
• Avoid excessive use.
• Stop and seek advice if significant irritation develops.
• Consider a gentle conditioner if the hair becomes dry.

Using too much salicylic acid can cause dryness, redness, or irritation.

How Coal Tar Shampoo May Help

Coal tar has been used for many years to treat psoriasis. It can help reduce scaling and itching and may be particularly useful for some people with scalp psoriasis. 

Coal tar products can have drawbacks, including:

• Strong odor
• Hair dryness
• Temporary staining of light-colored hair or clothing
• Increased sensitivity to sunlight
• Skin irritation in some people

The American Academy of Dermatology recommends stopping coal tar and contacting a dermatologist if severe burning, swelling, or worsening psoriasis occurs. 

Tips For Using Medicated Shampoo

Using a medicated shampoo gently can help reduce irritation. Scratching or aggressively rubbing the scalp can worsen psoriasis and may contribute to temporary hair loss.

Helpful habits include:

• Massage shampoo gently into the scalp.
• Avoid scratching or picking scales.
• Follow the recommended contact time.
• Rinse thoroughly.
• Alternate with a gentle non-medicated shampoo when appropriate.
• Use conditioner to help reduce dryness.

The AAD recommends alternating medicated and non-medicated shampoos when needed to help prevent excessive dryness of the hair and scalp. 

When Prescription Treatment May Be Needed

Over-the-counter shampoos may be useful for mild scalp psoriasis, but stubborn or widespread symptoms may require additional treatment. Dermatologists can prescribe medications applied directly to the scalp, including corticosteroids and other psoriasis treatments. 

Professional evaluation may be appropriate when:

• Symptoms do not improve.
• Thick plaques continue to build up.
• Itching becomes difficult to manage.
• The scalp becomes painful or irritated.
• Hair loss becomes noticeable.
• Psoriasis extends beyond the scalp.

A dermatologist can determine whether the condition is psoriasis or another scalp disorder and recommend an appropriate treatment plan.

Shampoos for scalp psoriasis can be useful for managing scaling and itching, particularly products containing ingredients such as salicylic acid or coal tar.  However, shampoo alone may not be enough for moderate or severe scalp psoriasis.

Use medicated shampoos according to their directions, treat the scalp gently, avoid scratching, and consider professional evaluation when symptoms persist or worsen. A dermatologist can recommend treatments based on the severity and characteristics of the scalp psoriasis.
